A client of mine contacted me with this problem. His Outlook data file was in another computer as a shared file on a peer-to-peer (no server) network, both computers running under Windows XP Pro. However he was getting an access error when trying to open Outlook. The error was of course not verbose enough to troubleshoot anything.

But when I tried to open the shared folder containing the data file from the remote computer, I got a more detailed error. “Not enough server storage is available to process this command”. Ok I can work with that.

The problem had nothing to do with Outlook as you probably gathered. It didn’t even had anything to do with the computer running Outlook. The target computer, the one hosting the shared file, was acting as a server. However due to a registry problem, it was unable to provide access to the file. So, registry editing time. Added the appropriate entry to it, restarted, problem vanished. Another happy customer.

Contact me if you have a similar problem and need help resolving it.
